laravel使用关系在多个表中插入数据

用户将同时在事故、车辆表中添加数据

我设法将数据添加到事故表中，但没有添加到我的代码所在的车辆上

用户型号：

class User extends Model implements Authenticatable{

     use \Illuminate\Auth\Authenticatable;

     public function accident(){
         return $this->hasMany('App\Accident');
     }
}

class Accident extends Model{

     public function user(){
         return $this->belongsTo('App\User');
     }
     public function vehicle(){
         return $this->hasMany('App\Vehicle');
     }
}

class Vehicle extends Model{

     public function accident(){
         return $this->belongsTo('App\Accident');
     }
 }

 public function postAccident(Request $request){

    $accidentLocation = $request['location'];
    $accidentDateTime = Carbon::now('Asia/Manila')->format('y-m-d g:i:s A');

    $accident = new Accident();
    $accident->accidentLocation = $accidentLocation;
    $accident->accidentDateTime = $accidentDateTime;

    $request->user()->accident()->save($accident);

    $vehicle = new Vehicle(); // <-- Im trying to do this
    $vehicle->vehicleType = "SUV";

    $vehicle()->save();

    return response()->json(['msg' => "Successfully submitted"], 200);  

}

事故模式：

class User extends Model implements Authenticatable{

     use \Illuminate\Auth\Authenticatable;

     public function accident(){
         return $this->hasMany('App\Accident');
     }
}

class Accident extends Model{

     public function user(){
         return $this->belongsTo('App\User');
     }
     public function vehicle(){
         return $this->hasMany('App\Vehicle');
     }
}

class Vehicle extends Model{

     public function accident(){
         return $this->belongsTo('App\Accident');
     }
 }

 public function postAccident(Request $request){

    $accidentLocation = $request['location'];
    $accidentDateTime = Carbon::now('Asia/Manila')->format('y-m-d g:i:s A');

    $accident = new Accident();
    $accident->accidentLocation = $accidentLocation;
    $accident->accidentDateTime = $accidentDateTime;

    $request->user()->accident()->save($accident);

    $vehicle = new Vehicle(); // <-- Im trying to do this
    $vehicle->vehicleType = "SUV";

    $vehicle()->save();

    return response()->json(['msg' => "Successfully submitted"], 200);  

}

车型：

class User extends Model implements Authenticatable{

     use \Illuminate\Auth\Authenticatable;

     public function accident(){
         return $this->hasMany('App\Accident');
     }
}

class Accident extends Model{

     public function user(){
         return $this->belongsTo('App\User');
     }
     public function vehicle(){
         return $this->hasMany('App\Vehicle');
     }
}

class Vehicle extends Model{

     public function accident(){
         return $this->belongsTo('App\Accident');
     }
 }

 public function postAccident(Request $request){

    $accidentLocation = $request['location'];
    $accidentDateTime = Carbon::now('Asia/Manila')->format('y-m-d g:i:s A');

    $accident = new Accident();
    $accident->accidentLocation = $accidentLocation;
    $accident->accidentDateTime = $accidentDateTime;

    $request->user()->accident()->save($accident);

    $vehicle = new Vehicle(); // <-- Im trying to do this
    $vehicle->vehicleType = "SUV";

    $vehicle()->save();

    return response()->json(['msg' => "Successfully submitted"], 200);  

}

我的控制器和数据：

class User extends Model implements Authenticatable{

     use \Illuminate\Auth\Authenticatable;

     public function accident(){
         return $this->hasMany('App\Accident');
     }
}

class Accident extends Model{

     public function user(){
         return $this->belongsTo('App\User');
     }
     public function vehicle(){
         return $this->hasMany('App\Vehicle');
     }
}

class Vehicle extends Model{

     public function accident(){
         return $this->belongsTo('App\Accident');
     }
 }

 public function postAccident(Request $request){

    $accidentLocation = $request['location'];
    $accidentDateTime = Carbon::now('Asia/Manila')->format('y-m-d g:i:s A');

    $accident = new Accident();
    $accident->accidentLocation = $accidentLocation;
    $accident->accidentDateTime = $accidentDateTime;

    $request->user()->accident()->save($accident);

    $vehicle = new Vehicle(); // <-- Im trying to do this
    $vehicle->vehicleType = "SUV";

    $vehicle()->save();

    return response()->json(['msg' => "Successfully submitted"], 200);  

}

车辆：

public function up()
{
    Schema::create('accidents', function (Blueprint $table) {
        $table->increments('id');
        $table->timestamps();
        $table->string('accidentLocation', 100);
        $table->dateTime('accidentDatetime');
        $table->string('weatherCondition', 30);
        $table->string('accidentCase', 20);
        $table->string('roadCharacter', 20);
        $table->string('roadCondition', 20);
        $table->string('collisionType', 20);
        $table->string('accidentType', 20);
        $table->integer('vehicleNumber');
        $table->string('accidentStatus', 10);
        $table->text('file_attachment');
        $table->string('user_id');
    });
}

 public function up()
{
    Schema::create('vehicles', function (Blueprint $table) {
        $table->increments('id');
        $table->timestamps();
        $table->integer('accident_id')->unsigned();
        $table->foreign('accident_id')->references('id')->on('accidents');
        $table->string('vehicleType', 20);
        $table->string('vehicleMake', 20);
        $table->string('vehicleModel', 20);
        $table->string('vehiclePlateNumber', 10);
        $table->string('vehicleClassification', 15);
        $table->string('vehicleOwner', 50);
        $table->string('vehicleRegistration', 30);

        $table->integer('driver_id')->unsigned();
        $table->foreign('driver_id')->references('id')->on('drivers');
    });
}

使用

elount

关系保存数据

public function postAccident(Request $request){

    $accidentLocation = $request['location'];
    $accidentDateTime = Carbon::now('Asia/Manila')->format('y-m-d g:i:s A');

    $accident = new Accident();
    $accident->accidentLocation = $accidentLocation;
    $accident->accidentDateTime = $accidentDateTime;

    $request->user()->accident()->save($accident);

    $vehicle = new Vehicle(); // <-- Im trying to do this
    $vehicle->vehicleType = "SUV";

    // Save the vehicle associates accident
    $accident->vehicle()->save($vehicle);



    return response()->json(['msg' => "Successfully submitted"], 200);  

}

$incident->vehicle（）->save（$vehicle）；这是正确的

我删除了$table->integer（'driver_id'）->unsigned（）；

---

$table->foreign（'driver_id'）->references（'id'）->on（'drivers'）；它能工作

错误是什么？而不是

$vehicle（）->save（）

TRY

$incident->vehicle（）->>attach（$vehicle->id）
